摘要： An exposure apparatus according to this invention uses, as a correction value, the difference between a threshold current obtained from the light emitting characteristics of a single laser light source when only the single laser light source emits a laser beam, and a threshold current obtained from the light emitting characteristics of the single laser light source when the single laser light source emits a laser beam while the bias currents are supplied to the remaining laser light sources other than the single laser light source. The exposure apparatus uses the correction value to correct bias currents and switching currents determined by APC, and exposes the surface of an image carrier with laser beams output from the plurality of laser light sources based on the corrected bias currents and switching currents.

摘要： A printing system includes printing apparatuses connected to a network. A control apparatus of the printing system may send a print job to each printing apparatus and instruct each printing apparatus to execute the print job. When a first printing apparatus is instructed to execute the print job, the control apparatus makes a substitute printing reservation. The substitute printing reservation is for a second printing apparatus to execute the print job instead of the first printing apparatus. The second printing apparatus is set to a waiting state in which the second printing apparatus waits to execute the print job instead of the first printing apparatus.
